  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: First-line RAS wild-type metastatic colorectal cancer patients

Who may be able to join

  • Aged ≥ 18 years, regardless of gender.
  • Histopathologically and radiologically-confirmed metastatic colorectal cancer with RAS wild-type status (wild-type for KRAS and NRAS exons 2, 3 and 4; if test records are limited, the exact test scope and testing method should be documented); and the participant is planned to receive FOLFOX combined with either Panitumumab N01 or cetuximab/cetuximab N01.
  • At least one measurable lesion assessable per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1).
  • No prior anti-tumor therapy for colorectal cancer, including chemotherapy, radiotherapy, targeted agents, surgery and immunotherapy. Participants with disease recurrence and metastasis > 3 months after completion of adjuvant chemotherapy or prior local treatment of the primary lesion are eligible.
  • Availability of at least one record of follow-up, clinic revisit, prescription, billing settlement, or imaging assessment after administration of study drug.
  • Possession of a de-identified unique identifier enabling linkage between clinical data and medical insurance settlement data.

Waiver of informed consent is permitted if approved by the local Institutional Review Board / Independent Ethics Committee (IRB/IEC).

Who cannot join

  • Patients with brain metastasis accompanied by cognitive impairment, those with concomitant neuropsychiatric disorders, a history of substance abuse, alcoholism or illicit drug use, or any other conditions that would interfere with study follow-up and outcome assessment.
  • Patients with known hypersensitivity, contraindication or precautionary use to the study treatment agents, their analogues, or other biological products.
  • Pregnant or lactating females.
  • Patients who have participated in another interventional clinical study within 4 weeks prior to the first dose or during the study exposure period (the exposure period is defined as from the date of administration of the index study drug to 28 days after the last dose; the half-life of the index drug is approximately 7 days), and received investigational anti-tumour agents such as other anti-EGFR monoclonal antibodies or other biological targeted agents; such co-administration would prevent clear attribution of efficacy or costs within the exposure period.
  • Patients with critical missing key variables, including RAS status, treatment regimen and index date, precluding the primary analysis.

About this study

Official title: A Real-World Study of FOLFOX Combined With Panitumumab N01 Versus Cetuximab as First-Line Treatment for RAS Wild-Type Metastatic Colorectal Cancer

This is a prospective, observational, multicenter cohort study. Subjects will be divided into the Panitumumab N01 group (experimental group) and the cetuximab or cetuximab N01 group (control group) according to the treatment they actually receive. Both groups will receive FOLFOX chemotherapy. Real-world follow-up data will be used to comprehensively evaluate clinical efficacy, safety and health economic outcomes between the two groups.

No fewer than 610 patients planned to receive first-line treatment for colorectal cancer with FOLFOX combined with Panitumumab N01 or cetuximab/cetuximab N01 will be enrolled (305 patients in the cetuximab/cetuximab N01 arm and 305 patients in the Panitumumab N01 arm). After enrollment, medical records of participants will be collected, including baseline characteristics, laboratory test results, radiological assessments, medication history and survival status, with follow-up continuing until March 2030. Adverse events will be collected up to 28 ± 7 days after the last dose to capture potential safety events. Follow-up schedule: survival will be confirmed by telephone monthly in accordance with routine clinical practice at local sites; clinical follow-up every 3 months is recommended for patients discontinuing treatment for reasons other than disease progression.

This study will not alter the established clinical decisions of treating physicians or impose additional treatment risks on patients. All treatment regimens will be administered in accordance with clinical guideline recommendations and individual patient clinical circumstances.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. overall survival

    Time from the index-date (initial diagnosis of RAS wild-type mCRC) to death from any cause. Patients alive or lost-to-follow-up will be censored at the date of last valid follow-up.

    Measured: From date of first diagnosis of RAS wild-type metastatic colorectal cancer until date of death from any cause, assessed up to 30 months

  2. Incremental Cost-Utility Ratio (ICUR)

    Ratio of incremental direct medical costs versus incremental quality-adjusted life-years (QALYs) between the Panitumumab N01 arm and the cetuximab/cetuximab N01 arm; unit: CNY per QALY. Only costs generated after Panitumumab N01 is listed for national medical reimbursement are included.

    Measured: From date of treatment initiation until date of study completion, death, or loss to follow-up, whichever comes first, assessed up to 30 months

Secondary outcomes (17)
  1. 2-Year Overall Survival Rate

    Cumulative probability of being alive at 24 complete months after index-date, estimated by the Kaplan-Meier method. All-cause death is the event; subjects who are lost-to-follow-up or still alive before 24-month time-point are censored.

    Measured: From date of first diagnosis of RAS wild-type metastatic colorectal cancer until date of death from any cause, assessed up to 24 months

  2. Real-World Progression-Free Survival

    Time from index-date to the earliest documented disease progression (per real-world clinical evidence: imaging, pathology, clinical notes indicating PD / new lesion) or death from any cause, whichever occurs first. Censored at last evaluable assessment for patients without events.

    Measured: From date of first diagnosis of RAS wild-type metastatic colorectal cancer until date of first documented disease progression or death from any cause, whichever comes first, assessed up to 30 months

  3. Duration of Treatment

    Time from first dose of study drug (Panitumumab N01 / cetuximab / cetuximab N01) to permanent discontinuation of study drug for any reason (disease progression, adverse event, patient preference, economic reason, death).

    Measured: From date of first administration of study drug (panitumumab N01 or cetuximab / cetuximab N01) until date of permanent treatment discontinuation for any cause, assessed up to 30 months

  4. Time To Next Treatment

    Time from index-date to initiation of next-line systemic anti-tumor therapy or death, whichever occurs first. Maintenance therapy is not counted as next-line treatment.

    Measured: From date of first diagnosis of RAS wild-type metastatic colorectal cancer until date of initiation of next-line systemic anticancer therapy or death from any cause, whichever comes first, assessed up to 30 months

  5. Objective Response Rate

    Proportion of participants achieving best overall response of Complete Response (CR) or Partial Response (PR) per RECIST 1.1, sustained for at least 4 weeks, from index-date until documented disease progression or initiation of participant's new anti-tumor therapy.

    Measured: From date of first diagnosis of RAS wild-type metastatic colorectal cancer until date of disease progression or initiation of new anticancer therapy, whichever comes first, assessed up to 30 months

  6. Complete Response Rate

    Proportion of participants achieving best overall Complete Response (CR) per RECIST 1.1, sustained for at least 4 weeks, from index-date until documented disease progression or initiation of participant's new anti-tumor therapy.

    Measured: From date of first diagnosis of RAS wild-type metastatic colorectal cancer until date of disease progression or initiation of new anticancer therapy, whichever comes first, assessed up to 30 months

  7. Disease Control Rate

    Proportion of participants achieving best overall response of CR, PR or Stable Disease (SD) per RECIST 1.1, sustained for at least 4 weeks, from index-date until documented disease progression or initiation of participant's new anti-tumor therapy

    Measured: From date of first diagnosis of RAS wild-type metastatic colorectal cancer until date of disease progression or initiation of new anticancer therapy, whichever comes first, assessed up to 30 months

  8. Early Tumor Shrinkage Rate

    Proportion of participants with ≥30 % reduction in sum of longest diameters of measurable target lesions at Week 8 ± 7 days after participant's first study-drug dose (RECIST 1.1). No minimum duration of response required.

    Measured: At 8 weeks ±7 days after the participant's first study-drug dose

  9. Depth of Response

    Maximum percentage-reduction from baseline in sum of longest diameters of target lesions among participants with tumour shrinkage. Formula: (baseline sum - minimum on-treatment sum of target-lesion longest diameters) / baseline sum × 100 %.

    Measured: From baseline assessment until the time point of maximum tumor shrinkage during the entire treatment period, assessed up to 30 months

  10. Conversion Resection Rate

    Percentage of participants who had MDT-confirmed initially unresectable metastatic colorectal cancer at baseline and subsequently received curative-intent resection of all primary plus metastatic lesions after receiving ≥1 cycle of study treatment.

    Measured: From participant's baseline MDT assessment until completion of participant's curative-intent surgery

  11. Cancer-Specific Survival

    Time from index-date to death attributable to colorectal cancer or treatment-related complications. Deaths from other causes are treated as competing events; participants lost-to-follow-up or remaining alive are censored. Estimated via Fine-Gray competing-risk model

    Measured: From participant's first study-drug dose to 28 days ± 7 days after participant's last study-drug dose

  13. Per-Patient Full-Cycle Direct Medical Costs

    Per-participant total direct anti-tumour-related medical costs from index-date to death, including targeted-drug cost, chemotherapy cost, pre-medication cost, adjunctive-drug cost, lab-imaging costs, inpatient costs, outpatient costs and adverse-event-management costs.

    Measured: From date of treatment initiation until date of study completion, death, or loss to follow-up, whichever comes first, assessed up to 30 months

  14. Per-Patient Medical-Insurance-Fund Payment Amount

    Per-participant total amount paid by medical-insurance funds (pooling fund, catastrophic-insurance, medical-assistance, supplementary-enterprise-insurance)

    Measured: From date of treatment initiation until date of study completion, death, or loss to follow-up, whichever comes first, assessed up to 30 months

  15. EQ-5D-5L Health-Utility Value

    Health-state utility value derived from the Chinese EQ-5D-5L value set, covering mobility, self-care, usual-activities, pain-discomfort, anxiety-depression; score range -0.594 ~ 1.0 (1 = full health, 0 = death; negative values represent states worse-than-death).

    Measured: Assessed at baseline, weekly for the first 2 months of treatment, every 3 months (±7 days) during subsequent treatment, and every 6 months (±14 days) after disease progression, through study completion, up to 30 months

  16. FACT-EGFRI-18

    Patient-reported 18-item FACT-EGFRI-18 questionnaire evaluating EGFR-inhibitor-associated physical, social-family and functional symptom burden over the prior 7 days; total score and sub-domain scores (physical well-being, social-family well-being, functional well-being). Higher scores represent lower symptom burden and better quality-of-life

    Measured: At baseline within 28 days before the participant's first study-drug dose; weekly for the first 2 months of the participant's treatment; every 3 months ± 7 days thereafter; up to 28 days ± 7 days after the participant's last study-drug dose

  17. PRO-CTCAE Adverse-Event Outcomes
